JAMES EASTERLY, OF ALBANY, NEW YORK.

GRA'IE FOB COAL-STOVES.

Specification of Letters Patent No. 21,410, dated September 7, 1858.

To all whom it may concern:

Be it known that I, JAMES EASTERLY, of Albany, in the county of Albanyand State of New York, have invented a new and improved mode ofconstructing the grates for coal-stoves, by which they are betteradapted to be agitated on a level to shake the ashes and slag from thefire, and tilted to empty the furnace; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings and to the letters of reference markedthereon.

In constructing this improvement, it was assumed that the most effectivemethod of cleaning the ashes and slag from the furnace while it is inaction is to vibrate and agitate the grate on a level. But it is equallyimportant to have a convenient method of tilting the grate to empty thefurnace, and also to have it so adapted, that it can be removed from thefurnace, for repairs or for other purposes, without the inconvenience ofunmounting the stove.

The nature of my improvement consists in constructing the grate, and thebar on which it rests, and combining therewith a clasp spanning the bar,to be permanently connected to the grate, having a projection extendingout parallel with the bar to receive a lever with which the grate may beagitated on a level, and by connecting a lever to the end of the bar thegrate may be tilted to a perpendicular position and empty the residuumfrom the furnace.

To enable others skilled in the art to make and use my invention, I willdescribe its construction and operation.

Of the annexed drawings, Figure -1, is a front elevation, and Fig. 2, avertical section, with the stove above the furnace broken off. Fig. 3,is a plan of the same.

A is the furnace, B the grate, L L is a bed plate which supports thelining and the grate.

C is a bolt connecting the grate to bar D, and by the nut M, on bolt C,the grate is kept in place.

H is a clasp spanning bar D, and is to be permanently connected to theperiphery of the grate, and have a projection extend ing out parallelwith the bar, to near the front of the ash pit, and perforated at I, toreceive a lever J.

F is a sink or bearing in plate L L,

at the back side of the stove, in which one end of bar D, is to rest.

G is a clasp or hearing to hold the end of bar D in place at the frontof the stove. hen adapted in this manner, the grate (by the use of leverJ) may be agitated as shown by red dotted lines on Fig. 3, and

when necessary the lever J may be connected to bar D at E, and the gratetilted to a perpendicular position, as shown by red dotted lines on Fig.1, to empty the residuum from the furnace. The bar D is suspended acrossthe ash pit eecentrically, that the grate may have a secondary bearingon plate L L, by projection K, and preyent it from tilting when beingloaded with uel.

I am aware that stoves have heretofore been used with the grate restingat its center on a bar suspended across the ash pit, and so adapted thatthe grate could be agitated .on a level by the use of a lever or tiltedto empty the furnace by turning the bar. Such grates, so far as I am acquainted, have not been used with the bar extending from front to rearof the stove, but with those only having a bar extending across the ashpit. Such an arrangement of grate and bar is open to several objections.If the bar projects through the side of the stove to receive a lever fortilting the grate, it is not only a deformity, but the grate and barcannot be removed from the stove for repairs, or for other purposes,without the inconvenience of having the stove unmounted, which destroysthe lining and also produces other inconveniences not necessary tospecify, or if the bar sustaining the grate does not project through theside of the stove, but only rests on the plate which supports thelining, what they (the grate and bar) may be removed for repairs, or forother purposes, without unmounting the stove. It must be apparent thatother inconveniences arise. A lever purchase cannot be used for tiltingthe grate, and consequently there is much difficulty in tilting it whenloaded with fuel, and as a still further objection it is necessary tohave the door of the ash pit open while tilting the grate, therebyallowing dust to flow out and diffuse itself over the room, whereas withmy improved device we not only have a grate that its whole fixture maybe removed through the ash pit opening for repairs, or for otherpurposes, by simply detaching bearing G, holding the bar in place I atthe front of the stove, but We also have a grate that can be agitatedthrough a small opening to the ash pit, and thereby avoid dust, and bythe employment of a lever the grate may be tilted when the ash pit isclosed, thus entirely avoiding dust While agitating the grate forcleaning the ashes and slag from the fire, and When tilting it to emptythe furnace, and also, by the use of a lever, be enabled to tilt thegrate Without difii culty when loaded With fuel.
